Frequently Asked Questions

AI
NPT (National Pipe Tapered) threads create a seal by wedging together, often requiring sealant tape. Flare fittings use a flared tube end and a matching cone-shaped plug to create a mechanical seal without tape.
No. Silicone rubber plugs are generally intended for sealing holes, powder coating, or low-pressure liquid applications. For gas or high-pressure systems, always use brass or steel threaded plugs.
GHT (Garden Hose Thread) is a coarse thread specifically designed for hose connections, whereas NPT is a standard pipe thread. They are not interchangeable and will not seal properly if mixed.
